摘要
将变色酸比色法中催化剂浓硫酸和显色剂变色酸的加入顺序加以调整,充分利用反应过程中浓硫酸的发热量,减少分析过程中的能耗,减少样品分析时间,提高样品的分析效率。
Change the join order of the catalyst sulfuric acid and chromogenic agent chromotropic acid, make full use of concentrated sulfuric acid calorific value in whole reaction process, reduce the energy consumption in analysis process, reduce the time of sample analysis expend, improve the sample analysis efficiency.
